  • Polarization preserving front projection screen microstructures
    Patent number: 8004758
    Abstract: Polarization preserving front projection screens and diffusers provide optimum polarization preservation for stereoscopic 3D viewing, as well as improved light control for enhanced brightness, uniformity, and contrast for both 2D and 3D systems. Generally, the disclosed screens direct light from a projector toward viewers within a diffusion locus, while maintaining optimum gain characteristics. More specifically, light incident on a region of the front projection screen from a predetermined projection direction is reflected by an engineered surface to a predetermined diffusion locus after undergoing substantially single reflections. The engineered surface, comprised of generating kernels, is used to optimally diffuse illumination light into a range of viewing angles, within the diffusion locus, with suitable gain profile, while optimally preserving polarization for 3D applications.

  • Systems and methods for back end of line processing of semiconductor circuits
    Patent number: 8003519
    Abstract: A BEOL manufacturing process for forming a via process between two metal lines on a semiconductor wafer comprises depositing a portion of a first metal adhesion layer within a patterned via hole, followed by a cooling step. The cooling step is then followed by formation of the remainder of the first metal adhesion layer and formation of a second metal adhesion layer within the patterned via hole. This process of forming the remaining portion of the first metal adhesion layer can be referred to as a wafer load, unload, load (LUL) process. By using a LUL process, thermal history is minimized, which reduces Al extrusion at the via interfaces.

  • Source reputation information system with router-level filtering of electronic messages
    Patent number: 8001268
    Abstract: Disclosed herein are filtering systems and methods that employ an electronic message source reputation system. The source reputation system maintains a pool of source Internet Protocol (IP) address information, in the form of a Real-Time Threat Identification Network (“RTIN”) database, which can provide the reputation of source IP addresses, which can be used by customers for filtering network traffic. The source reputation system provides for multiple avenues of access to the source reputation information. Examples of such avenues can include Domain Name Server (DNS)-type queries, servicing routers with router-table data, or other avenues.

    Abstract: The present application describes a system and method for driving a power supply device in an initial activation stage. In one embodiment, the method comprises providing in the power supply device at least one voltage regulator that is coupled with a voltage output adapted to supply a power voltage to a client device, receiving a signal indicative of an activation of the power supply device, and converting the at least one voltage regulator to an equivalent shunting circuit coupled between the voltage output and a reference voltage. Before power voltages are applied at the outputs of the power supply device, shunting paths are thus provided for releasing undesired currents.
